A Geo Passive world of the Dwarf Terrestrial Group. These are silicate worlds which are generally barren and lifeless with little to no geological activity.
Their surfaces are very hot, and in some cases reaches temperatures which allow the formation of molten metal lakes on the surface. These may produce enough volatiles to form a trace atmosphere of heavy metals.
They are often good targets for mining.
Silicates and related compounds are abundant, along with ferric orcs and heavy metals within the crust.
